摘要
针对短波通信系统中的抗衰落和抗干扰问题,分析了4FTSK调制及解调技术,设计了以数字信号处理器DSP作为实现平台,根据4FTSK的调制解调原理,运用对应的算法直接在芯片内部实现调制与解调。试验表明该方法简单灵活,性能稳定。
As to the anti-fading and anti-jamming in the short-waving communication system, the paper analyzes the modulation and demodulation technology of 4FTSK, and designs a system which is based on digital signal processor as a platform. According to the modem principle of 4FTSK, the modem can be directly realized in the chip by the corresponding algorithm. The experiment shows that the method is of simplicity, flexibility, and good performance.
